CHRISTOPHER BUCKELS | 9 Triangles, Tropes, and τὰ τοιαʋ ̃τα: A Platonic Trope Theory Christopher Buckels University of California [email protected] ABSTRACT A standard interpretation of Plato’s metaphys- ics holds that sensible particulars are images of Forms. Such particulars are fairly indepen- dent, like Aristotelian substances. I argue that this is incorrect: Platonic particulars are not Form images but aggregates of Form images, which are property-instances (tropes). Timaeus 49e-50a focuses on “this-suches” (toiauta) and even goes so far as to claim that they compose other things. I argue that Form images are this- suches, which are tropes. I also examine the geometrical account, showing that the geomet- rical constituents of the elements are also Form images. Thus everything in the sensible world is composed of tropes.

As will become objects are composed of microscopic three clear in the paper, I take Timaeus’ metaphysics dimensional objects, which are, in turn, of particulars to be a version of a trope theory, composed of two‑dimensional objects. Most, and so I take τὰ τοιαῦτα to be tropes, but I will if not all, properties of macroscopic objects are defend this claim in the fourth part; I will also explained by properties of microscopic objects, consider the traditional account of particulars which are in turn explained by the configu in the Timaeus whereby Form images are bod ration of two‑dimensional objects. We seem ies (i.e., physical objects) rather than tropes. to have a completely reductionist, naturalist Let me begin by giving an initial character account of the world; why, then, is it accompa ization of a Platonic trope theory. Tropes are nied by supernatural entities such as Platonic often used to avoid commitment to universals; Forms? While I will explain why Forms are the universal or Form Whiteness, for example, crucial for the account of particulars in the could be the set of all whiteness tropes. Most Timaeus, I will be focusing not on Forms, but trope theories, therefore, are nominalist theo on sensible particulars, the three‑dimensional ries. Timaeus is not, of course, a trope nomi objects we bump into on a day‑to‑day basis, nalist; his tropes coexist with transcendent as well as their constituents. I will argue that universals, Forms.1 In his terms, a trope is a Plato does not take these particulars as basic “this‑such” (τὸ τοιοῦτον) or Form image — constituents of the physical world, but that the a trope‑theoretic interpretation of Timaeus’ ultimate constituents of Timaeus’ sensible par ontology is thus not anachronistic, since he ticulars are what metaphysicians call tropes, himself introduces tropes, as I will show, albeit or property‑instances; Timaeus calls them τὰ under the name of “this‑suches” (τὰ τοιαῦτα).2 τοιαῦτα, “this‑suches.” My argument follows: When one feels hot, one does not feel heat in general but a particular heat, this heat: a heat 1.

All and only things that come to be but a particular entity, distinct from each are images of Forms. other instance of heat. This is what I mean by 3. Therefore, τὰ τοιαῦτα (this‑suches) are a trope: a particular, non‑repeatable instance images of Forms. of a property. 4.
